This allows mesa to set the tiling format for a BO and have that tiling format be respected by mesa on the other side of an import/export (and by vc4 scanout in the kernel), without defining a protocol to pass the tiling through userspace. Signed-off-by:

The T tiling format is what V3D uses for textures, with no raster support at all until later revisions of the hardware (and always at a large 3D performance penalty). If we can't scan out V3D's format, then we often need to do a relayout at some stage of the pipeline, either right before texturing from the scanout buffer (common in X11 without a compositor) or between a tiled screen buffer right before scanout (an option I've considered in trying to resolve this inconsistency, but which means needing to use the dirty fb ioctl and having some update policy). T-format scanout lets us avoid either of those shadow copies, for a massive, obvious performance improvement to X11 window dragging without a compositor. Unfortunately, enabling a compositor to work around the discrepancy has turned out to be too costly in memory consumption for the Raspbian distribution. Because the HVS operates a scanline at a time, compositing from T does increase the memory bandwidth cost of scanout. On my 1920x1080@32bpp display on a RPi3, we go from about 15% of system memory bandwidth with linear to about 20% with tiled. However, for X11 this still ends up being a huge performance win in active usage. This patch doesn't yet handle src_x/src_y offsetting within the tiled buffer. However, we fail to do so for untiled buffers already. Signed-off-by:

According to the eLCDIF initialization steps listed in the MX6SX Reference Manual the eLCDIF block reset is mandatory. Without performing the eLCDIF reset the display shows garbage content when the kernel boots. In earlier tests this issue has not been observed because the bootloader was previously showing a splash screen and the bootloader display driver does properly implement the eLCDIF reset. Add the eLCDIF reset to the driver, so that it can operate correctly independently of the bootloader. Tested on a imx6sx-sdb board. Cc: <stable@vger.kernel.org> Signed-off-by:

If one 'drm_gem_handle_create()' fails, we leak somes handles and some memory. In order to fix it: - move the 'free(bo_state)' at the end of the function so that it is also called in the eror handling path. This has the side effect to also try to free it if the first 'kcalloc' fails. This is harmless. - add a new label, err_delete_handle, in order to delete already allocated handles in error handling path - remove the now useless 'err' label The way the code is now written will also delete the handles if the 'copy_to_user()' call fails.

drm_irq.c contains both the irq helper library (optional) and the vblank support (optional, but part of the modeset uapi, and doesn't require the use of the irq helpers at all. Split this up for more clarity of the scope of the individual bits. v2: Move misplaced hunks to this patch (Stefan). Cc: Stefan Agner <stefan@agner.ch> Reviewed-by:

The driver is written in a way to enable compile-testing without CONFIG_ARM_AMBA, but it just causes needless warnings: drivers/gpu/drm/pl111/pl111_drv.c:149:26: error: 'pl111_drm_driver' defined but not used [-Werror=unused-variable] drivers/gpu/drm/pl111/pl111_drv.c:81:12: error: 'pl111_modeset_init' defined but not used [-Werror=unused-function] This unhides the probe/remove functions again and just leaves the driver object as unused when CONFIG_ARM_AMBA is disabled, with a __maybe_unused annotation to shut up the warning.

drm_atomic_set_mode_for_crtc() doesn't modify the passed mode, so let's make it const. Signed-off-by:
